FLAT-FOLD BINDER DEVICE.

Our invention relates to leaf-attaching clips for fiat-fold bindings, and has for an object, the provision of clips adapted to be rigidly secured to the back cover member of o a binding, and which will be of simple and economical construction, and readily applied.

A further object of our invention is to provide a clip for a fiat-fold binder WhlCll is better adapted for permanently securing,

lo the leaves in place than are otherclips known to us.

i More specific objects and advantages of our invention will appear in the following specification. The invention is illustrated in the accompanying drawing,wherein,-

Figure 1 is a side elevation of-a portion of a leaf binding with a clip embodying out invention applied thereto, the blnding being shown by full lines in its open position and in its closed position by dotted lines.

Fig. 2 is a side elevation of one of the clips, shown detached; Fig. 3 is an end elevation of Fig. 2; and Fig. 4: is a horizontal sectional view on the line 44.- of Fig. 2. Fig. 5 is a plan view of the washer member shown in Fig. 1. Fig. 6 is a fragmentary underside plan view of a binder board wlth clip applied thereto in its" unsecured rela: tion; and Fig. 7 is a view of the parts shown in Fig. 6,but illustrating the clip as secured to the binder board.

The binderproper maybe ofany known or suitable constructionand as shown comprises a bottom board 10, a top'board 11, and, preferably, a'backing board 12 which are hingedly connected together as bymeans of a piece of fabric 13, or an equivalent, which is glued or otherwise secured to the respective board members. 1 Such flexible binding permits the board members to be laidas represented by full lines 1n Flg. 1 in a plane, or flatwise, upon a table; or to be arranged in a folded condition, as indicated by full lines 10, and dotted lines 11 and 12 in the referred to view.

Secured to the bottom board in spaced apart relation transversely thereof is a plurality of clips such as 14. These CllPS are each made from wire, preferably circular in cross section, and is bent or otherwise formed, to substantially the shape of an inverted capital letter U, thereby providing two parallel side legs 15 and 16. Said legs have their lower ends 15 and 16 or prongs as hereinafter termed, of less .the check stubs C S and which upon bein thickness than the diameter of the material in the upper or body portion of a clip.

Said legs are formed by cutting away or pressing the respective legs to produce the prongs below shoulders 17 and 17 which is disposed intermediate the height of the clip and in a plane at right angles to the axes of the respective legs. -As shown, the prongs are in transverse section of a segmental shape, each having a circular arcuate sur- 135 face 18 and 18 (see Fig. 1) and plane chord surfaces 19 and 19 i These prongs are, moreover, disposed oppositely one with the otherthat is to say, the arcuate side of one prong is at one side and the arcuate side of the other prong is at the other side of the clip. I

Cooperating with said clip is a washer or bearing plate 20 of an oblong shape (see Fig. 5) with apertures 21 therein having cross sectional areas and shapes corresponding to that ofthe prongs 15 and 16 and suitabl located to accommodate the latter.

In practice, theinvention is usually employed for securing banklchecks, asC, Fig.

1, through the medium ofthe attached check stubs C S to and within a binder- For which purpose, oneleg of each cli is first threaded through apertures provided in 0' thus seized, are coupled to the bottom board 10 of the binding by passing both pron s of the several clips through the bearing p ates,

as 20,.and the bottom board 10 successively, and, finally, bending theprongs 15 and 16 into-clenching relation against the under surface of the board 10.

In regulating a clip with respect to the associated bearing plate 20, care should be taken to have the. shoulders 17 .17 bearagainst the plate whereby the turning over or clenching of the prongs against the board 10 as explained above will serve to draw the plate and board into clamping relation therewith and rigidly. support the clip in loo 7 vertical position. It is to be noted that by positioning the shoulders 17, 17 at opposite sides of the legs, permits the pron s to be turned in. opposite directions so that the plane 'surfaces 19, 19 of both-prongs may be juxtaposed with the bottom of the board 10 whereby afirm conection is had between a clip and a binder board, with a rounded protruding portion of the pron s below the binder-,which allows the bin or to be in close proximity to :atablc or other support besides =obviatingzdanger of the prongs catching against any object when the binder is slidably moved upon the support. v 7

1 Fig: "1' we" illustrate the manner which are done after the checks have been removed. When the checks-are removed the stubs may be swung over upon the inverted back board 12 as represented by C 3 .at the left hand side of Fig. l. The binding remaining flat wvhile these operations are Q3 Cir bein eriormed.

The inventlon and the unanner of applying and using the same will be understood "from the toregoing specification.

Vhile we have illustrated and described the invention in its 'form now preferred by us we do not wish to beunderstood as confining ourselves specifically therewith except as limited by-the scope of the appended claims.

I What we claim, is- V .1. In a binding for leaves, leaf attaching means comprising a plurality o'tclips oi." an inverted ,U-shape,:each of said clips being formed to provide alegs with shoulders dise posed intermediate their lengths, each of said legs below the respective shoulder constituting prong-adapted -ito' penet-ra'te a binder board, said prongs being of ,greater length-than the thickness ofthe board to afiord protruding end-s adapted for bending to bear against the under surface of the board td-cooperate with said shoulder to Lela-mp the board therebetween.
